ABSTRACT:
Springs and straps laterally and vertically buttress lateral buttock support wings of a motorcycle seat. The springs are flat and sinuous and extend slightly upward and outward from the seat pan to support the seat wings. Straps secure to the springs and pass inwardly from them through a hole in the pan to an anchor point for the straps underneath the pan. The length of the straps is adjustable to adjust the lateral distance between the springs in the wings and the response to force applied to the springs. The straps restrain the springs in their spreading under rider load. The looser the straps the more the springs deflect vertically and laterally under rider load.
